Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.
Pros and cons of using cannabis clones
You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.
Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.
After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

If there are any seeds that have not finished germinating, leave them in a moist place until they sprout.
One benefit of the soil method is that transferring the seedling to a bigger pot is simple. The cannabis is less likely to become stressed and can adapt to the new environment quickly. A disadvantage would be needing to buy clean soil rather than using some from outside. Pathogens in the dirt can damage the young seedling. Soil density can be an issue with air flow, and growers need to be careful about the seed placement.
How Long Does It Take for Cannabis Seeds to Germinate
The seedling plugs and cubes already come moist. However, the setback is they dry out over time. Once you open a package, you have over a week to use them. Many products do not provide less than 50 cubes. If you plan to germinate only a few seeds, you could end up wasting a lot of cubes. Therefore, this method can be less cost-effective than others.
One benefit of the paper towel method is that you can leave sprouted seeds in the towel for a while longer. It allows other seeds to catch up, and you can plant them all at once. Otherwise, you can plant the germinated ones as soon as the taproot appears.
Some cannabis growers use Rockwool cubes to germinate weed seeds. The method requires some setup before you can plant the seeds. Start by filling a bowl with some water. Use some pH-balancing chemicals to bring the water down to around 5.5. You may need a test kit to measure the levels.
